Source§fn from_string(s: &str) -> Result<Self, Error>
fn from_string(s: &str) -> Result<Self, Error>
Create an instance from a string literal in a value position.
fn from_nested_meta(item: &NestedMeta) -> Result<Self, Error>
Source§fn from_meta(item: &Meta) -> Result<Self, Error>
fn from_meta(item: &Meta) -> Result<Self, Error>
Create an instance from a
syn::Meta by dispatching to the format-appropriate
trait function. This generally should not be overridden by implementers. Read moreSource§fn from_none() -> Option<Self>
fn from_none() -> Option<Self>
When a field is omitted from a parent meta-item,
from_none is used to attempt
recovery before a missing field error is generated. Read moreSource§fn from_word() -> Result<Self, Error>
fn from_word() -> Result<Self, Error>
Create an instance from the presence of the word in the attribute with no
additional options specified.
Source§fn from_list(items: &[NestedMeta]) -> Result<Self, Error>
fn from_list(items: &[NestedMeta]) -> Result<Self, Error>
Create an instance from a list of nested meta items.
Source§fn from_value(value: &Lit) -> Result<Self, Error>
fn from_value(value: &Lit) -> Result<Self, Error>
Create an instance from a literal value of either
foo = "bar" or foo("bar").
This dispatches to the appropriate method based on the type of literal encountered,
and generally should not be overridden by implementers. Read morefn from_expr(expr: &Expr) -> Result<Self, Error>
